Donald Corey Patterson (August 13, 1979 in Atlanta, Georgia) is an American professional baseball outfielder with the St. Louis Cardinals of Major League Baseball. He is the older brother of outfielder Eric Patterson.

That year, he had a batting average of .528 with 81 runs scored, 22 home runs, 61 RBI and 38 stolen bases in 38 games.

Patterson was selected by the Chicago Cubs as the third overall pick in the 1998 Major League Baseball Draft. He made his professional debut in 1999 with the Lansing Lugnuts of the Class-A Midwest League, and was selected as that league's "Prospect of the Year" after leading the league in slugging percentage (.592), extra base hits (72) and triples (17).
